AITA for not rescuing my son

I have a son, Nick, age 15. He’s a great teenager. We have him do normal chores around the house like his sister. My wife and I are pretty easy on them when it comes to chores, and we don’t care about stuff like making their beds. Whatever. <br><br>I’m a pretty firm believer in letting kids fail. I think there’s a lot of good in it and I let both of my kids have failed in small ways over the years. Examples of this include not rescuing them when they forget stuff or making them do poorly on a test because they didn’t read the instructions.<br><br>Nick had a project for school. It was to make a colonial village. Nick and I worked on this the night before. Nick is very crafty and has always been good at making things. I was involved whenever he had questions about painting or stuff like that. <br><br>Nick finished the project around 10, put it in his room and went to bed. Nick also had a basketball game the next morning. It was an early game and Nick and his friends decided to sleep over to make it easier. Nick gave the project to his friend and told him to bring it to school. <br><br>I didn’t know any of this and I’m asleep around 8. I wake up early and Nick has texted me that he needs the project. His friend had forgotten to bring it and that they were already on the way to the hoops tournament. <br><br>His friend was 45 minutes away by the time we realized. I told Nick I wasn’t driving it and if he walked out of his room I’d consider it. I fell back asleep. Nick called a few times begging me to bring it but I didn’t answer. <br><br>Nick texted that his friend was driving back to get it. I texted Nick back that I’d consider it his problem when his friend got back at 10:30. Nick was absolutely frantic. I told him to go to sleep to stop worrying. <br><br>I think if you have the chance for your kid to fail and learn from it, that’s a good thing. I put this project together and I know that they pick projects like this so that kids can put them together and have them for years to come. I also had a project like this when I was Nick’s age. <br><br>Nick texted around lunch that his friend turned his phone off and that he was in danger of failing. I told him he can try to reach his friend and that I’d be happy to take him to school. He ended up getting a zero on the project. <br><br>His friend got a zero too and his dad isn’t happy, and I told him that I will not rescue Nick and I let him fail when I can. Nick is pissed but he’ll come around. His friend is pissed too. <br><br>AITA?
